Question

Find the length of the third side. If necessary, round to the nearest tenth.
15
20

Answer 1

Answer: The third side has a length of 25 units.

Explanation:

In a right triangle, we can use
`a^2+b^2=c^2` to find the side length of c.

`15^2+20^2=c^2`

225 + 400 = 625

`\sqrt 625` = 25

Therefore, c = 25.
